Definitions

  • the present invention relates to a flocked yarn which has a good touch and a high abrasion resistance and which is suitable for use in home interia and various industrial fields and a method for manufacturing the flocked yarn.
  • Japanese Utility Model publications SHO 36-22141, SHO 41-16437 and SHO 47-32904 disclose improved core yarns for a flocked yarn, respectively.
  • Japanese Utility Model publication SHO 43-5155 discloses an improved adhesive for use for combining a core yarn and flock fibers.
  • Japanese Utility Model publication SHO 52-131073 discloses improved materials for a flocked yarn.
  • JP-B-SHO 47-19579, JP-A-SHO 51-84955 and JP-A-SHO 61-15757 disclose respective apparatuses for manufacturing flocked yarns.
  • Flocking which utilizes static electricity is performed such that flock fibers with an electric charge fly along lines of electric force formed in an electrostatic field and parts of the flown flock fibers are forcibly plunged into a layer of an adhesive applied onto the periphery of a core yarn, see e.g. GB-A-1 148 700.
  • the flocking is continued until the conveyed flock fibers cannot plunge into the layer of the adhesive because the flock fibers lose their movement by losing their charge by coming into contact with flock fibers already flocked. This state is usually called the "fully flocked state".
  • the amount of lines of electric force (electric flux) formed on the surface of a core yarn to be flocked is desirably as uniform as possible all over the surface of the core yarn in order to achieve the above state (that is, fully flocked state) as early as possible. Even if the amount of lines of electric force formed on the surface of the core yarn to be flocked is slightly nonuniform, it is desirable to be able to fully flock the flock fibers on the core yarn only by extending the flocking time to some extent.
  • the electric flux density per unit square of the surface of a substrate material to be flocked can be uniformalized by providing an electrode having a surface shape conforming to that of the substrate material on which the flock fibers are to be anchored, or in a case where the substrate material has a columnar shape such as a core yarn, by rotating the columnar substrate material (a core yarn).
  • a cylindrical electrode is required and/or a columnar substrate material must be rotated in these methods, these methods have a limitation in simultaneous treatment of a plurality of substrate materials. Therefore, these methods lack practicability in the production of flocked yarns.
  • a flocked yarn according to the present invention comprises a core yarn the total denier of which is in the range of 140-1260 (about 154-1386 d tex), a layer of adhesive applied onto the periphery of the core yarn, and flock fibers with a length of 0.5-3.0 mm which are flocked onto the layer of adhesive at a flocking density of at least 30,000/cm2, the weight in grams A of adhesive per 9,000 m of core yarn satisfying the equation. 27.5 D ⁇ A ⁇ 72.5 D
  • D is the total denier of the core yarn.
  • a method for manufacturing a flocked yarn according to the present invention comprises the steps of applying a layer of adhesive onto a core yarn, the total denier of which is in the range of 140-1260 (about 154-1386 d tex) in an amount by weight satisfying the equation (I), and flocking flock fibers onto the layer of adhesive by a method in which flocking of the flock fibers onto the adhesive layer is controlled by subjecting the fibers in turn to an electrostatic field in which an attractive force operates and an electrostatic field in which a repulsive force operates.
  • This controlled flocking may be carried out by a method (1) which comprises
  • Step (iii) may be carried out merely by changing the polarity of one of the electrodes after the performance of step (ii).
  • the method lends itself particularly to a continuous process in which the steps (ii) and (iii) are carried out alternately for respective intervals of time as the core yarn passes continuously between the electrodes.
  • Step (ii) may be carried out by applying a positive voltage to one of the pair of electrodes, and a negative voltage to the other of the pair of electrodes, and step (iii) may be carried out by changing the polarity of the voltage applied to one of these electrodes so that an electrostatic field in which an attractive force and a repulsive force alternately operate is formed between the pair of electrodes by the pole change of one of the pair of electrodes.
  • An alternative continuous method (2) of flocking comprises
  • a positive voltage may be applied to one such electrode, and a negative voltage to the other so that an electrostatic field in which an attractive force operates is formed between the electrodes of the first pair, and in the second pair of electrodes, one of a positive voltage and a negative voltage may be applied to both electrodes so that an electrostatic field in which a repulsive force operates is formed between the second pair of electrodes.
  • a first pair of electrodes generate the electrostatic field in which the repulsive force operates and a second pair of electrodes generate the electrostatic field in which the attractive force operates.
  • a core yarn to which an adhesive has been applied is introduced between at least one pair of electrodes which face each other, and flock fibers are flocked by utilizing two kinds of electrostatic field systems in combination.
  • a first electrostatic field system which is as usually used, a positive voltage is applied to one of the pair of electrodes and a negative voltage is applied to the other of the pair of electrodes. Because of the attractive force between electrodes of the pair, attractive lines of electric force are formed, and the flock fibers are conveyed to the core yarn along these attractive lines of electric force.
  • a positive or negative voltage is applied to both electrodes of the pair. Because of the repulsive force between the electrodes of the pair, repulsive lines of electric force are formed and the flock fibers are conveyed to the core yarn along these repulsive lines of electric force.
  • the flock fibers are flocked onto the periphery of the core yarn with a uniform and high flocking density by using the two kinds of electrostatic field systems in combination.
  • a good flocked yarn may be obtained wherein flock fibers with a cut length of 0.5-3.0 mm are flocked, at a flocking density of at least 30,000/cm2, onto a core yarn the total denier of which is in the range of 140-1260 (about 154-1386 d tex).
  • the arrangement of electrodes is not particularly restricted.
  • a pair of electrodes may be arranged in a vertical direction or in a horizontal direction.
  • two or more pairs of electrodes may be arranged in the running direction of a core yarn, as long as at least a pair of electrodes form an electrostatic field therebetween in which an attractive force operates and at least another pair of electrodes form an electrostatic field therebetween in which a repulsive force operates.
  • a positive or negative voltage may be applied to one of the pair of electrodes and the other of the pair of electrodes may be grounded.
  • a plurality of core yarns are simultaneously introduced between a pair of electrodes from the viewpoint of productivity.
  • the plurality of core yarns may be arranged in a single plane or may be arranged in many planes.
  • the flock fibers are conveyed along lines of electric force formed in electrostatic fields in which an attractive force operates and in which a repulsive force operates, and the conveyed flock fibers are plunged into and flocked onto a layer of an adhesive applied onto a core yarn which has been introduced into the electrostatic fields.
  • the intervals of the time (cycle) for which the attractive force operates and the time for which the repulsive force operates may be decided in dependence upon the particular characteristics of flock fibers and core yarn to be used, and are not particularly restricted because a sufficiently adequate operation can often be achieved even if the intervals (cycle) are (is) relatively short.
  • a sufficient amount of flock fibers must be suspended in the electrostatic fields, that is, a sufficient flock fiber mist must be formed in the electrostatic fields, in order to obtain a sufficient flocking density of a flocked yarn.
  • One is the so-called “down flow” system wherein flock fibers are supplied downwardly to an electrostatic field and the other is the so-called “up flow” system wherein flock fibers are supplied upwardly to an electrostatic field.
  • a conventional flock fiber dropping apparatus may be used.
  • For use in the up flow system there are methods for lifting flock fibers upwardly by an attraction electrode and by an upward air flow, and further by combining these two methods.
  • the system for forming the flock fiber mist is not restricted by the above systems or methods.
  • the adherent amount of adhesive on a core yarn must satisfy the equation (I) to achieve a sufficient penetration of the flock fibers into the layer of adhesive on the core yarn. 27.5 D ⁇ A ⁇ 72.5 D Further, the equation (II) is preferably satisfied. 35 D ⁇ A ⁇ 65 D
  • D is the total denier of the core yarn and A is the weight (g) of the adhesive per 9,000 m of core yarn.
  • the amount of adhesive determined by equation (I) is fairly large in comparison with the amount of adhesive which is used in a conventional manufacture of a flocked yarn. If the amount of adhesive is smaller than the above amount determined by equation (I), it is difficult to cause penetration of the flock fibers into the layer of adhesive with a sufficient penetration depth because the core yarn generally has a fine columnar shape and the flock fibers already flocked obstruct the penetration of new flock fibers. If the amount of adhesive is larger than the above amount determined by equation (I), it is required to increase the viscosity of the adhesive in order to form and maintain a uniform and concentric circular layer of adhesive around the core yarn. However, when such a high-viscosity adhesive is used, flock fibers become difficult to anchor to the adhesive layer and to penetrate sufficiently into the layer. Thus, the adequate range of the amount of adhesive is determined as represented by equation (I).
  • the total denier of a core yarn of a flocked yarn according to the present invention must be at least 140 (about 154 d tex) from the viewpoint of ensuring its sufficient tensile strength and abrasion resistance. On the other hand, the total denier must be at highest 1260 (about 1386 d tex) in order to make the handling and treatment of the core yarn easy and in order to obtain a flocked yarn having a good feeling ("touch").
  • the total denier of the core yarn is preferably in the range of 210-840 (about 231-924 d tex).
  • the core yarn is usually constructed of a plurality of individual fibers.
  • the denier of the individual fiber is usually in the range of 0.5-10 (about 0.55-11 d tex), but it is not particularly restricted.
  • the cut length of flock fibers must be at least 0.5 mm because it becomes difficult to obtain a flocked yarn having a good touch and a high abrasion resistance if the cut length is shorter than the above figure.
  • the cut length of flock fibers must be at longest 3.0 mm because it becomes difficult to anchor the flock fibers into the layer of adhesive with a sufficient depth and the flocking density of the flock fibers decreases if the cut length is greater than the above figure.
  • the cut length of the flock fibers is preferably in the range of 0.7-2.0 mm.
  • the denier of a flock fiber is not particularly restricted, but it is preferably in the range of 1-15 (about 1.1 to 16.5 d tex) from the viewpoint of ensuring a good touch of an obtained flocked yarn.
  • the materials for the core yarn and flock fibers according to the present invention are not particularly restricted and various materials can be applied, for example, a natural fiber such as a cotton, wool or bast fiber, a synthetic fiber such as a polyester fiber, a polyamide fiber or an acrylic fiber, a regenerated cellulose fiber such as a rayon, a bemberg (a trademark), a semisynthetic fiber such as an acetate or a protein fiber, and an inorganic fiber such as a carbon fiber or a glass fiber etc.
  • the core yarn and the flock fibers are desirably constructed from an identical material, and the material is preferably a synthetic fiber represented particularly by a nylon fiber having a high elasticity against compression.
  • the materials of the core yarn and flock fibers may be different from each other.
  • the adhesive combining a core yarn and flock fibers may be any adhesive which can strongly combine the material of the core yarn and the material of the flock fibers and which does not impair flexibility and good touch of an obtained flocked yarn.
  • the adhesive is one of an acrylic ester adhesive and a urethane adhesive.
  • an optimum amount of adhesive may be applied to a core yarn, the flying direction of the flock fibers is adequately changed in the electrostatic fields in which both an attractive force and a repulsive force operate, and the flock fibers are anchored onto the layer of adhesive with a high flocking density and a sufficient penetration depth. Therefore, a flocked yarn in which the flock fibers are uniformly flocked and which has a high flocking density and a good touch can be obtained. Further, since the flock fibers are sufficiently and strongly combined with the core yarn, the obtained flocked yarn can have a high abrasion resistance.
  • FIG. 1 schematically illustrates the cross section of a flocked yarn 1 according to an embodiment of the present invention.
  • Flocked yarn 1 comprises a core yarn 2 which is constructed of multifilaments and the total denier of which is in the range of 140-1260 (about 154-1386 d tex), a layer of an adhesive 3 applied onto the periphery of the core yarn, and flock fibers 4 flocked onto the layer of the adhesive.

  • This flocking apparatus 24 is of the up flow type and is equipped with a pile containing box 25 at a bottom portion thereof.
  • Flock fibers 4 present in the pile containing box 25 are suspended as a flock fiber mist in a flocking room 28 by being blown up by a flow of air supplied from an air inlet 26 and by upward attraction by a lift electrode 27 provided above the pile containing box.
